VALE STI-XE HAEFFNER, OF DOBBS FERRY, NEW' YORK.

IMPROVED BEER-COOLER..

Specicatiouforming part of Letters Patent No. 37,443, dated January 20, 1863.

To all rwhom it muy concern: Be it known that I, VALENTINE HAEFFNER, of Dobbs Ferry, in the county of West-chester 1 and State'ofNew York, have invented a new and Improved Beer-Cooler; and I do hereby declare that the following is a full, clear, and exact description ofthe same, reference being had tothe accompanying drawings, forming al part of this specication, in whiche- Figure 1 represents a longitudinal vertical section of my invention; Fig. 2, a plan or top view ofthe same.

Similar letters of reference in both views indicate corresponding parts. A

This invention consists in the arrangement of a series of semicircular metallic `troughs placed at certain distances apartf so as to leave spaces for the air to circulate in, and-connected at their' ends by similiar transverse troughs` in combination with pipes passing` To Venable those `skilled in tle art to make and use my invention, I will proceed to delscribe it ivith reference to thedrawin gs.

A A represents a series of semicircular troughs, made of sheet-copper or other suitable material and of equal length, their ends being connected lby similar troughs, B, which extend at right angles to the troughs A, and whichI are closed at their ends, as clearly shown in Fig. 2 oi' the drawings. The troughs A are` so arranged that they are separated from each other by spaces ai, thereby allowing the air to circulate freely all round the t' same. The interior of the troughs A B is partially occupied by aseries of pipes, C .0', the pipes C being connected at right angles to the pipes C, andthe whole series being so arranged that they fit nicely in the troughs A I3, each pipe being situated in the center,or nearly so, of one ofthe troughs and charged through the pipes c', the current ,of

the cooling-liquid being in' a direction against that of the liquid to be cooled. I-n passing `through the troughs A B the beer or other yliquid to be cooled is divided up in annmber of small streams or thin tubular strata, being exposed on the inside to the sides 'of the pipes C Us', which are kept cool by the cold Water` or other liquid passing-through them, anden the outside to the sides of the troughs, which .are exposed allround to the injiuence ofthe atmospheric air, so that any heat which may lbe imparted to them is rapidly carried off by radiation. By these means the beer or other liquid is rapidly cooled While passing through troughs' of a comparatively short length. Without the air-spaces a between the troughs, and if said troughs are either separated simply by partitions, or if all the troughs are.merged. into one large trough, the material from which said trough is made is soon brought to the same temperature as the hot liquid and l the process of cooling is edected very slow4 or'o'nly by theaid of a large and costly apparatus. The application or use of the air-spaces ct between the troughs enables me to complete the process ot cooling beer or other liquid in an apparatus much smaller, and consequently much cheaper, than an apparatus of the ordinary construction. y n

If desired. two or more of my apparatuses may be placed oneou top of the other, and the beer or other liquid, after having passed through the upper or first apparatus, discharges into the second, and so on and itis` obvious that in this case the length of the several troughs can be materially reduced, and the whole apparatus can thus` be accommodated to the room or space in which it is to be used.

Instead of the transverse troughs B, short elbow-connections might be used to connect the ends ofthe adjoining troughs A, and in this case'the beeror other liquid would pass used' in combina-tion with-coldwatel' pipes C, through' the troughs inv a zigzag or serpentine substantially in the' manner andi'or the purohannel. pose herein shown and described. l Having .thus fully described 'my invention, what I claim as new; and desire to secure by VALENTINE HAEFFNER' Letters Patent, isl Witnesses:
